The objective of this research project was to demonstrate and evaluate the feasibility of treating undiluted heat treatment liquor prior to its rerouting back to the head of the sewage treatment plant. Chemical and biological treatment processes were studied. Chemical treatment was effected by the addition of hydrated lime followed by clarification both in bench-scale facilities and at full-scale in a 3200 gallon reactor. Biological treatment was achieved in a 2800 gpd high rate activated sludge pilot plant. Heat treatment liquor was generated by a Zurn heat treatment system, 16 gpm, at the Mentor, Ohio, wastewater treatment plant.
